T. D. SADLER HANDSAW GUIDE Fil'ed Jan. 16,. 1924 5 Sheets-Sheet 3 wwwkor the like is preferably accommodate a pair ol' liller blocks 18. Theclosely7 spaced apart ends ot the straps constitute the inner' end oitthe handle, and the straps carry a screw 14; provided with a winged nut15 adapted to clamp the strap ends together, and upon a measuring blade1G whichis pivotally mounted on the screw 141 and adapted to be swungthereupon into different angles, such as illustrated in Figure 2. Afriction washer 1T of leather interposed between the upper face ot theblade 1G and the upper strap of the handle,so as to frictionally bindthe blade 1G in adjusted position. A. retaining washer 1S is mountedupon the lower end oi the screw 14C and between the head ot the saine,and the lower strap ot' the handle.

The handle 11 is adapted to be held and clamped against the edge oit thework y a clan'ipingbar 19 which, as best shown in Figures 2 and Ll,comprises a Hat strip et apart to metal having a down-turned outer end2O 'forming a clamping jaw adapted to engage over the edge ot' the work10 remote :trom the handle 11. Theclamping bar is adapted to extendthrough a guide, slot 21 formed in the handle 11 intermediate the endsot the enlarged part thereof, and the slot 21 is Jformed in a bushing9:2 seated in the upper bloc-klo. The block 13 is provided with a wearplate Q3 at its outer side and above the slot 21. The lower edge ot' thewear plate f2?) is oll'set inwardly to provide a recess -t in the platein which is adapted to work the nose o'li' a clamping and lockingl leverrlhe locking lever 25 comprises a tlat bar o'l suitable length and widthfor easy handling,and which has rounded opposite ends forming nosesarranged to engage in the depression 2d one at a time, and the lever hasextending 'from opposite sides headed studs 2G, which are spacedunequally from the adjacent ends of the lever 25 to provi-de workingnoses ot different lengths. The studs extend from opposite sides otthelever 25, so that when one stud is extending downwardly,-tlie otherstud is extending upwardly to 'form a handle. The clamping bar 19 isprovided with a series of openings 27 of a size adapted to snuglyreceive the heads ot the studs 26 therethrough, and the studs 26 havingtheir shanks ot sntlicient length to permit the overlapping oit` theheads ot the studs against the lower side ol the clamping bar 1S), atterthe lever 25 has been fitted in the selected opening 27.

The studs 26 are so arranged with respect lo the adjacent ends ot' theclaini'iing lever as to torni therewith cams` so that utter the lever 25is fitted into an adjacent opening 2T at the outer side ot the handle13, the lever 25 may be swung outwardly into the position shown inFigures 1, 2 and t, so as to first draw the clamping bar 19 through thehandle 11 and bind the claw 2O ot the may be readily had metal `forming`a thickened back clamping bar against the work, and to then lock theclamping bar in such position by moving the lever 25 into a dead centerposin tion. After this is done the blade 16 n'iay at which it After thisis then The saw engaging member inay be ot any suitable constructionadaptable :tor mounting upon the blade 16, but in the present case isshown as con'iprising a yoke or body portion QS composed oit a pair otangle ineinliers having base portions 29 adapted to rest directly uponthe tace ot the work 1t), and having their major portions extending np-rwardly in closely spaced apart relation, and secured in such relativepositions by a bridge piece 230, which connects the upper ends ot theangle members. This yoke is adapted to receive therein a blade 31 ot asaw as shown in Figures 1 and 7. The angle members are provided atopposite edges with inwardly and oppositely facing vertical guide ways32, which may be formed with removable strips 33 at their outer sides,so that access l to the guide ways 32.

Slides 3st are mounted in the guide ways 32, and are in the form otspaced apart blocks 35 connected together at their upper endsr` andhaving` mounted therein a roller 3G arranged in the bight ot the slide`and adapted to engage the upper edge ot the saw blade 31. The lower endsot the blocks 35 have inwardly extending contact jaws 37 which areclosely spaced apart and adapted to engage against the opposite sides otthe saw blade 31, to hold the same from vibrating, and to also hold itin jtrne aline ment in the guide or yoke member 2S.

The back edge of the blade 31 is usually reinforced by an over-turnedstil strip edge for the saw and this enlarged edge is accommodated between the Contact jaws 37 and the roller 36, the latter bearing directlyon lthe edge and supporting the slide Sil on the saw. There is a slide34 provided at each end of the guide member 28, so that the slidesengage the saw blade 31 at longitudinally spaced points to thus maintainthe saw blade in true alinement, and prevent rthe lateral. de AIlectionthereof by the hand during the act ot reciprocating the saw.

The slides Het are adapted to rise and `tall with the saw blade not onlyin its rocliting and reziiirocating nioven'icnt. but also in thepositioning ot the saw at dillferent angles on the work. ri`hcadvantages ot such a structure. is that the bottoni ot the saw guide isopen, so that the saw blade may be inclined at the desired convenientangle and it does not necessarily have to be held in a true horizontalposition, such as is the case when using the ordinary type of mitre box.

and a winged nut 59 mounted on the bolt 55 may be used for clamping theblade 57 firmly to the handle when adjusted.

lt will be noted that there are no projections above the upper faceplate 51 of the block or handle so that the blades 53 and 57 may beswung` lengthwise of the handle and the try-squaremay then be packed ina small space or in a shallow tool chest or the like.

The adj usting blade 53 carries a removable saw guide which comprises abase plate adapted to rest on the work, and which carries a second plate6l of reduced width and which is spaced frein the plate 60 by strips GQproviding a channel 63 between the plates G() and 6l. The channel 63 isof suitable dimensions for slidably receiving the blade 53 therethrough.rlhe plate Gl carries a bearing block di therein with an axis of thebearing extending transversely of the plate Gl and in which is disposedthe shaft portion (i5 of an upright G6 mounted on the outer end of theshaft portion and which carries a pair of spaced apart bars ($7securedtogether at their upper ends only by rivets 68 or the like andbetween which is clamped a spacing block 69. A guide way or groove 70 isthus formed between the bars 67 for the reception of a saw bla-de. Thegroove 70 is of sufficient width to snugly receive the saw blade, so asto hold it from vibrating withoutv interfering with its freereciprocating movement. rlhe bars 67 have inner opposite flat faces toguide the blade and determine its true position across the workaccording to the angle at which the blade 53 and the saw guide isadjusted.

lThe upright G6 is mounted on the shaft (i5 so that the upright with itsbars 67 may be swung toward the plane of the base plate- GO, so that thedevice may be compact and placed in a small compartment when not in use.In order to hold the upright 66 when raised, adjustable brace rods 71are provided, one at each side of the upright 66 having their upper endsattached to an eye TQ mounted on the upper end ofthe upright GG andhaving their lower ends secured tov eyes 73 which are carried by theframe or lower portion of the saw guide at opposite sides of the bearing64.

lVith this type of the device the parts may be readily folded intocompact form, so as to occupy but small space, and the parts may bequickly and easily set up and applied'to the work in different positionsof adj ust in ent.

'lhe clamping blade 57 may be provided withpencil receiving openings 74arranged in suitable position and relation for drawing parallel lines onthe face of the work when desired; i

lt is obvious that various changes and of blades adjustably rseaocemodifications may be made in the details of construction and design ofthe above spe cilically described embodiment of this invention withoutdeparting from the spirit thereof, suoli changes and modifications beingrestricted only by the `scope of the following claims lVhat is claimediszl.
